Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [1] [2]

A simple electronic circuit prototype on a breadboard Example of prototype in optoelectronics (Texas Instruments, DLP Cinema Prototype System) In electronics , prototyping means building an actual circuit to a theoretical design to verify that it works, and to provide a physical platform for debugging it if it does not.
The book also covers more recent developments, including topics like floating point math, operating systems, and ASCII. The book focuses on "pre-networked computers" and does not cover concepts like distributed computing because Petzold thought that it would not be as useful for "most people using the Internet", his intended audience.

The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time , mass storage , peripherals, and ...
